We couldn't afford to pay for my mom's dementia assisted living anymore. She moved into a tiny house next door to me. - Business Insider

This as-told-to essay is based on a conversation with Lori Bufka, 64, who is caring for her mother with dementia in Arizona. Assisted living became too expensive for her mother, so Bufka moved her into a trailer next to their home, where her mother would have enough space and safety. This interview has been edited for length and clarity.

I was a college professor and retired from a community college in Florida. I raised two boys, both of whom are married, and I have five grandchildren. I had retired to do van life with my partner, who has been with me for seven years. I realized, though, that you can only do so much van life before you need a place to come home to. So we bought a tiny house in Arizona.

I'm an only child, and my mom was in assisted living in California. When she went into assisted living, her veteran benefits and Social Security were enough to cover the cost of her care. She was in assisted living for over seven years, and she had sold her house and had some savings. The rate kept going up and up, and it was draining her savings.
